More on weather

Most New England snow storms are track-dependent - the amount and type of precipitation is mostly shaped by the location of the center of the low that's coming up the coast. If it stays close to and a bit to the left of the 40/70 sweet spot (40N, 70W),folks in central Massachusetts, particularly those north of Worcester, can expect a bunch of snow.
The storms this week ran right over us pretty much, opening the sluices for southern moisture.

The storm that's coming today has similar characteristics, such that the storm warnings are saying that areas above 800 feet can expect 5-9" of heavy wet snow. Below that elevation, folks will get a few slushy inches.
The elevation at our house is 735 feet; the center of town is 810.
